Poster: AutoThermKV: An Efficient User-Transparent In-Memory Management of Hot Data for Key-Value Stores
Log-structured merge-tree (LSM-tree) key-value stores rely on caching to mitigate multi-component lookups and long tails, yet block and KP caches are prone to compactioninduced expiry, and all three cache types suffer from scan pollution under LRU eviction. We present AutoThermKV, a two-level in-memory architecture tha...
